COSRX BHA 4% Blackhead+Niacinamide 2% Exfoliant Toner 3.38 fl.oz / 100ml, Korean Toner, Pore Minimizer for Enlarged Pores, For All Skin Types, Korean Skincare, Not Tested on Animals, Paraben Free

I've been using the COSRX BHA 4% + Niacinamide toner and overall it feels like a solid exfoliating step. It helps with clogged pores and blackheads without being too harsh, though there’s a slight tingling at first. My skin feels a bit smoother and looks less congested over time. It’s easy to use after cleansing with a cotton pad. At £17.01, it feels reasonably priced, especially with Prime delivery and returns. It’s not a miracle product, but a steady addition to a routine.

Good product

Significantly reduces appearance of blackheads from unclogging them from ontop of the nose area and drawing them out from other places on the face and body.This has lasted nearly a whole year shrinking pore size will purchase again if prices are reduced since it's also a lot cheaper in t-k max stores.

Absolutely love this. My pores are visibly smaller on my nose and tops of my cheeks. It really does get out the gunk! I have dry sensitive skin. Whilst I haven't felt a reaction to it, it can make your skin dry especially around the nose. But I've found the more I use it, I have better toleration of the serum and less flakiness. I use it twice a week on days when I don't use other actives.

Bought this as a more affordable alternative to Paula's Choice 2% BHA. It's not the same and not as good. Won't repurchase. Saying that Paula's Choice is too expensive so I continue to try and find something that delivers the same elsewhere!

It’s a great product, I use it only once or twice per week. I have sensitive skin which is very reactive, and while I use La Roche Posay toleraine sensitive products to keep my skin nourished - I do feel I need this once or twice a week to keep my pores a bit clearer. I often make sure I have used my gentle sensitive cleanser prior, to make sure my skin is hydrated, and then just apply a small amount with my finger tips to my T-zone and inner cheeks. I am undecided wether or not it is actually better than using a normal salicylic acid - supposedly the variation in this is gentler - however it causes my skin to flush and have residual redness the day after using (hence why I might only use it one or maybe two days a week) I have in the past used other gels and salicylic acid treatment products which seemed to sort out blackheads and also calm the skin. I wouldn’t say this is calming on me, despite the fact that it has additional ingredients intended to sooth and reduce redness (niacinimide etc) Because I only use the tiniest pump onto my finger tips, I feel like this bottle would last me years and years (probably will go out of date before I finish it) so it’s good value and worth a try

Great product, quick delivery

This product is amazing ive bought this a few times now I have tried others and this is the best, I have a few of corsx products and I have really sensitive skin,but this is amazing for me ,always getting compliments on how great my skin looks not like that Paula choice,which i was recommended,it did nothing but made my skin tingle and made me come out in under skin spots which I never get and like alot of other products ,but this one is best definitely recommend for those with such sensitive skin and if you wanna see results ✌️
